Feeds directly on the hydranths of Eudendrium racemosum (Ref. 116462), wherein it's stimulated to feed and prefers hydranths which have captured the plankton, thus ingesting both the plankton and the hydroid polyp---a combination of predation and kleptoparasitism, a type of competition of stealing already captured food items. This combination does not fit into existing classifications, thus called 'kleptopredation.' Despite being an opportunistic predator which uses hydroids to capture prey from the column, hydranth forms only a fraction of its diet by volume. Plankton form at least half of its diet.
Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae
Members of the order Nudibranchia are simultaneous hermaphrodites. Mating behavior: Both individuals darts their penis toward each other to induce one to act as a male and the other as the female. The victorious one to penetrate the body wall is the dominant male. Life cycle: Eggs are deposited on a substratum where they develop and hatch into (planktonic) vestigial veliger larval stage and further grow as adults.
